                <h1>Ball Bearings</h1>
                <p>In their basic form, ball bearings are comprised of an inner race, 
                  outer race and spherical balls. Ball bearings carry a point load, unlike
                  roller elements that carry a line load. A reduced contact surface area 
                  lowers friction effects and allows a ball bearing to operate at high 
                  speeds. However, a small contact area limits the load that the bearing 
                  is able to withstand. Deep groove ball bearings may be used if greater 
                  carrying capacity is required. Ball bearings can accommodate loading in 
                  both the axial and radial directions. Thrust ball bearings are designed 
                  to support loads acting in the axial direction while mast guide bearings
                  utilize thick outer rings to support large radial loads. Rubber, felt, 
                  and steel seals are used in harsh environments to keep lubricants 
                  contained while baring dirt from entering the bearing. Multiple rows of 
                  balls may be configured to resist axial displacement. If desired, ball 
                  bearings may be heat resistant, created out of polymer materials, or 
                  unground.  Unground ball bearings offer a cheap alternative to precision
                  bearings, but result in shorter service life. Ball bearings are 
                  commonly used in agriculture, construction, conveyor systems, fans, and 
                  paper making machines.</p>
